Особенности синусоидального тока
Features of the sinusoidal current

The most desirable form of the curve for instantaneous values of alternating current and tension is the sinusoidal form. In mathematics sinusoidal changes are considered as the simplest harmonious form of the batch process.

Что такое синхронное вращение?
What is the synchronous rotation?

If by means of any adaptation to disperse the magnet to field speed, i.e. to synchronous speed, then, having entered synchronism, the magnet will rotate with the field speed. Synchronous rotation is used in synchronous motors.
